SPECIFICATION forming part Vof Letters Patent No. 674,359, dated May 14, 1901.

Application filed October 10, 1900. Serial No. 32,613. (No model.)

T0 all whom t may concern,.-

Beit known that I; DAVID E. LAIN, a citizen of the United States, and a resident of Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in Printers Lock-Ups and Furniture, of which the following is a specification.

My invention relates to an improvement in printers lock-ups and furniture; and it consists of two channel-bars tongued and grooved to move longitudinally within each other. A conical cam-wheel lyingbetween the two bars finds a bearing on one barand engages with a rack on the other bar. The revolution of this cam extends the lock-up.

Reference being had to the accompanying sheet of drawings, in which similar characters refer to similar parts, Figure l is a plan view of my new lock-up with a portion of the upper part removed. Fig. 2 is a vertical crosssection of Fig. l on a plane through line XY. Fig. 3 is a side elevation in section on a medial vertical plane. Fig. 4 is a plan view of a portion of my new lock-up, in which the internal mechanism is slightly different from that illustrated in Figs. l and 3. Fig. 5 is a side elevation of Fig. 4 in section on a medial vertical plane. Fig. 6 is a plan view of the conical cam-wheel, and Fig. 7 is a side elevation of Fig. 6. l

In Figs. l and 3, A is the larger channelbar, and B is the smaller. Tongues C, on the outside of the sides of B, lie in grooves on the inside of the sides of A. The bars may thus move longitudinally on each other. One end of the bar B is provided with the foot B. A rack I I is formed in the bottom of bar B, and a bearing F is formed on the lower side of the upper part of bar A.

Now referring to Figs. 6 and 7, a circular disk D has a rounded periphery N and carries on one side the conical cam J J. Through its center is a cruciform keyhole H. The disk D is of a diameter slightly smaller than the width of the channel in bar B and easily lies in this channel. One edge of the disk D is placed in the bearing F in bar A, and the other edge is allowed to lie on the bottom of the channel in bar B, when the cam J J will lie in two of the teeth of rack I I. A pin P projects downward from the upper wall of bar A in such a position as to prevent the disk D from disengaging with the bearing F. A springS is fastened to the upper wall of bar A and presses downward on the disk D, tending to keep it in engagement with the rack I I. A hole E through the upper wall of bar A permits the entry of the quoin-key K into the keyhole H. When the key K.is engaged with the disk D, as in Fig. 3, if it be turned in a clockwise direction the cam J J, .working in the rack I I, will drive the bar B toward the position indicated in dotted lines, and it will hold itin any position thustaken. When it is desired to return the bar B to its former position, it can be pressed back while the disk is being turned in a counter-clockwise direction. Also to return the bar B quickly if the key K and disk D be turned about the bearing F by pressing backward on the key they will occupy the 'position indicated by dotted lines. Then the disk D being entirely above the rack I I the bars can move on each other without any obstruction.

In Figs. 4 and 5 the cylinder L" is free to turn in a hole in the upper wall of bar A and is held in place by the upset portion L in a countersunk portion of the hole. The cylinder L is so placed that it prevents the disk D from disengaging with the bearing F. A lip L' on the cylinder locks the disk D in engagement with the rack I I when the cylinder is turned in the position shown in Figs. 4 and 5. When not in this position, the disk can be turned about the bearing F by pressing back on the key K, as in Fig. 3. Acruci form keyhole H in cylinder L provides for the rotation of the cylinder by the quoin-key K. In other respects the operation of this form is similar to that of the form illustrated in Figs. l to 3, as above described.

I do not wish to be understood as limiting IOO between seid hers with the periphery of seid disk sented in said bearing and said oem engaged with said rack, means for holdingsaid oem in engagement with said mok, and means for revolving seid disk and said eem.

2. In a, printers look-up or similar device the combination of two channel-bars matched together to move only longitudinally on each other and together forming zt hollow bm', 2t hearing on one bar,l e rack on the other ber, a disk which hits a cam on one face and lies in the hollow between the two bars in such manner that the periphery of said disk xmty lie in and move in said bearing and the eem may engage with the teeth of seid rack, means for revolving seid disk in such manner that its periphery may move through said bearing while said eem moves in engagement with the teeth of said rack, me-ftns for swinging said disk in seid bearing which may disengztge said anni from said reak, and means which may serve to hold seid @am in engagement with seid mok.

3. In n printers look-up or similztr device the combination of two Channel-bars nmtehed together to move only longitudinally on each other mid together forming n hollow bei', e. bearing on one ber, et raek on the other bar, :t disk which has it eem on one fztoe and lies in the hollow between the two bars in such zt manner that the periphery of seid disk nifty lie in and move in seid bearing and the eem may engage with the teeth of said rack, means for revolving seid disk in such manner that its periphery may move through said bearing while said eem moves in engagement with the teeth of said rack, means for swinging seid disk in said bearing in sueh manner that' said earn may become disengaged from said rack, a Catch which may be moved over the edge of seid disk when seid eem is in engagement with said reuk, and means for moving said catch in engagement with seid disk.
